REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 516,743, dated March 20, 1894. Application filed July 3, 1893- Serial No. 479,515. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM W. MILLER, a citizen of the United States, residing at Noyo, Mendocino county, State of California,

have invented an Improvement in Reversi- -may be turned through an arc in a vertical plane to fit the stationary land-side at either limit of its movement.

My invention consists in the novel construction of the double mold-board and share, and the means for mounting, turning and looking it, as I shall hereinafter fully describe.

The object of my invention is to provide a reversible plow which is not only adapted for use on side hills, but is equally adapted for use on level ground, thus providing one implement capable of perfect use in either or both situations.

Referring to the accompanying drawing for a more complete explanation of my invention,the figure is a perspective View of my reversible plow.

A is the plow-beam having a downwardly bent rear extension at which has connected or formed with it the fixed land-side B.

C is the mold-board. This consists of a concaved piece having a rear extension 0 and forwardly projecting share extremities c, the counterpart of each other. These share extremities are preferably separate pieces as is customary, and they are secured tothe moldboard by straps c on the back, one of said straps on each side being extensions of the stops 0 of the shares. This concaved piece 0, as far as general shape is concerned, is practically two level-land mold-boards joined together, each half of thesingle mold-board servingits full purpose as an ordinary plow, thereby adapting the plow for perfect use on level land, the earth being turned by it completely over as with an ordinary level-land plow, thereby distinguishing it and its result from the usual side-hill plow, the efiect of which on level-land is merely to stand the earth on end and not to turn it over. This combined moldboard has secured to its back, at a point in the front of its horizontal central plane, a horizon tal axis or shaft D which is mounted in the lower end of the rear extension aof the beam, and in a vertical standard 0. extending between the beam and land-side. Said shaft can rockin its bearings and it has at its rear end a crank d by which it may be turned, by the manipulation of a pull rod d extending upwardly and resting between the handles E.

The width cf the mold-board is such that by reason of the position of its axis, it is enabled to turn under the beam through a vertical are from a vertical position on one side to a vertical position on the other side, and in each position its point or stop 0 fits the extremity of the land-side.

Arms F project from the back of the moldboard and each is adapted to engage with a hole bin theland-side to steady and brace the mold-board.

To hold the mold-board and lock it in position, there is a locking pin G, the forward end of which passes through the front extremity of the land-side, and is adapted to enter a socket in the stop 0 of the share ex-.

tremity. This pin is projected and retracted. by means of a lever H, with the lower end of which it is connected, as shown. The lever is pivoted at h to the plow beam, and it is held in position by means of a small hole in its under side which is sprung over a small pin a on the beam.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a reversible plow, the combination of a beam, a land-side carried by said beam at its rear end, a horizontal axis or shaft mounted in the beam above the land-side, and the laterally concaved plowbottom consisting of the mold-board and duplicate opposing share extremities, said mold-board being secured to the forward end of the axis or shaft in its horizontal central plane, and its share extremities having stops adapted to overlie and fit alternately the front extremity of the land-side and present a smooth and uninterrupted surface, substantially as herein described.

2. In a reversible plow, the combination of a beam having a down-turned rear extremity, a land-side secured thereto and a standard between said land-side and extremity, a horizontal axis or shaft mounted in the beam extremity and standard, the laterally concaved plow bottom, consisting of the moldboard secured to the axis or shaft, and duplieate-opposing share extremities, and the arms F of the mold-board adapted to alternately engage sockets in the land-side, substantially as herein described.

3. In a reversible plow, the combination of the beam and land-side, the concaved moldboard and duplicate opposing share extremities having socketed stops, said mold-board being mounted and adapted to turn on a horizontal axis, and the means for locking and relieving the mold-board, consisting of the pin seated in the land-side and adapted to be projected into and withdrawn from the socketed stops of the share extremities, and the pivoted lever connected with and operating said pin, substantially as herein described.

4. In a reversible plow, the combination with the beam and the land-side, the concave mold board and duplicate opposing share extremitieshaving socketed stops,said mold board being mounted and adapted to turn on a horizontal axis,'a rod G having a sliding engagement with the land-side and with its free end adapted to engage the mold board and lock it to the land-side, a lever pivoted to the beam for operating said rod, socketed stops carried by the opposing share extremities, arms F secured to the opposing sides of the mold-board and adapted to alternately engage sockets in the sides of the land-side, and a pull rod and crank for rotating said mold board, substantially as herein described.

In witness whereof I have hereunto set my hand.
